4 Claims.

This invention relates to a boat anchor.

An object of this invention is to provide an anchor which willefliciently operate on different types of lake bottoms, and have goodholding ability on every bottom.

Another object of this invention is to provide an anchor of constructionand weight that gives good holding power on tough clay, and which willdig into hard-packed sand, as well as having good holding power in softmucky bottoms.

With the foregoing and other objects in view, this invention comprisescertain novel constructions, combinations, and arrangements of parts aswill be hereinafter fully described, illustrated in the accompanyingdrawings, and more particularly pointed out in the appended claims.

In the drawings:

Fig. 1 is a view in side elevation of an anchor shank 2 is provided withtwo arms 3, which are turned inwardly at their inner ends 4, Fig. 5, andthese ends 4 are secured by bolts 5 to the inner face of the end B ofthe frame I. A weight I is is within the frame I, in front of ends 4,and this weight is secured in position by means of a bolt ii thatextends through the rear end of the frame I. This weight I is cut awayat 9 on its top and bottom, these cut-away portions 9 registering withthe arms 3 of the shank 2. As shown in Figs. 2, 4 and 5 these cut-awayportions are wider and deeper on the side of the member I than at theopposite side. A ring II! is mounted on the shank 2 and slides freely onthe arms 3. As is clearly shown in the drawings the diameter of thematerial of which the ring is made is less than the distance between thedeeper end of the cutaway 9 and the adjacent portion of the shank arm 3.The cut-away portions thus permit the ring It to move into positionbetween the weight I and an arm 3, the tapering of the cut-awayeffecting jamming or gripping of the ring in such position. When theanchor is in use, the usual chain or cable (not shown) is attached toring I0, and when the anchor is holding the boat in a relativelystationary position, the strain will be on the outer end of shank 2.When the operator wishes to move the boat, he operates the ring I0 untilit moves backward on one of the arms 3 until the ring is positioned inone of the cut-away portions 9, whereupon the anchor can be lifted toremove it from its anchoring position. In other words, the liftingposition is when the ring I0 is at the rear of the anchor, with the ringhaving a portion between one of the arms 3 and the weight 1.

Bolts II extend outwardly from the sides of the frame I. with theirinner ends extending through the sides. 0n the inner end of the boltsare nuts I2. A washer I3 is on each bolt against the fluke I4 and a nutI5 is on the bolt against the washer I3, Fig. 2. A bushing I6 is on eachbolt, Fig. 5, on which is loosely mounted the fluke I4. The washer I3 isagainst the outer end of the bushing It. The fluke I4 has a relativelyfree swinging movement on the bushing.

Each fluke I4 comprises an elongated plate having inner and outerflanges I1 and a second flange extending longitudinally thereof at thecenter section of said fluke plate as a reinforcing rib. Each-flukeplate I1 is cut away at I8. The frame I is also cut away at I9. Whenthefluke I4 is in its down position, Fig. 1, the cut-away portion I8 willbe engaging the cut-away portion I9. When the fluke I4is in its raisedposition, the cut-away portions I8 will bear against the front edge ofthe side of frame I.

The bolts II not only provide the means for mounting the flukes on theframe I, butthey also hold the anchor in an operative position,including the preventing of the anchor from turning over, which wouldretard the function of the anchor by reason of preventing the fiukesfrom digging into the ground.

While I have described the preferred embodiment of the invention andillustrated the same in the accompanying drawings, certain minor changesor alterations may appear to one skilled of plate metal having a centralportion and a pair of frame arms extending at right angles from saidcentral position, a shank formed from a strip of' flat metal bent at itscenter to provide an arcuate portion and having shank arm diverging fromthe arcuate portion and provided with inturned ends resting on thecentral portion of the frame, securing bolts extending the inturned endsand frame and holding the shank rigidly on the frame, a ring for cableattachment slidably engaged on said shank, stock arms projecting inalinement outwardly from the frame arms, and fluke members swinginglymounted on said stock. arms.

2. In an anchor of the class described, a frame of plate metal having acentral portion and a pair of frame arms extending at right angles fromsaid central position, a shank formed from a stripsof flat metal bent atits center to provide an arcuate portion and having shank arms divergingfrom the arcuate portion and pro-gidedwith intnrned ends resting on thecentral portion of the frame,

securing bolts extending the inturned .ends and frame and holding the.shank rigidly on the fra-me,.,a ring for. cable attachment slidably,engaged .onsaid shank, stock arms projecting in alinement outwardlyfrom the -frame arms, and fiukezmemberseach consisting ofan elongatedplatejhaving inner and outer flangesand asecond I:
